Question

Please consider this string list:

Afghanistan, Albania, Algeria, El Salvador,
Equatorial, Guinea, Eritrea, Estonia
Ethiopia, Panama, Papua, Paraguay
Peru, Togo, Trinidad & Tobago, Tunisia, Turkey

and I have another list:

tan, ia, Tu

I want all countries that contains tan or ia or Tu. How I can do this without foreach loop?

thanks

Answer 1

Try Linq which will perform the loop for you:

var apiKey = 'apikey';
var pageToken = '';
var numOfResult = 0;
var maxResults = 200;
function searchVideo(){
         var separator = ",";
         $.getJSON('https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&maxResults=50&pageToken=' + pageToken + '&playlistId=PLrEnWoR732-BHrPp_Pm8_VleD68f9s14-&key=apikey&callback=?',function(data){

                var l = data.items.length;
                pageToken = data.nextPageToken;
                numOfResult += l;
                var itemUrl = '';
                for(var i = 0; i < l; i++) {
                        if( i == 0) {
                                separator = ',';
                        }
                        else {
                                separator = ',';
                        }
                        var videoid = data.items[i].snippet.resourceId.videoId;
                        var title = data.items[i].snippet.title;
                        console.log(videoid);

                        var input_data = "<input type='hidden' value='" + videoid + "' name='videoid[" + i + "]'><input type='hidden' value='" + title + "' name='title[" + i + "]'>";
                        $("form").append(input_data);

                }

                if( numOfResult < maxResults) {
                        searchVideo();
                }
        });
}

Try something like that;

library(data.table)
as.data.table(data)[, .SD[any(Age >= 20 & Age < 30)], Household_id]
#    Household_id Household_relation Age
# 1:            2                  1  27
# 2:            2                  2  34
# 3:            4                  1  22
# 4:            4                  2  23
# 5:            7                  2  21
# 6:            7                  1  29
# 7:           11                  1  31
# 8:           11                  2  29

Also, I have ignored the case sensitive. If you want to perform case sensitive use var listA = new List<string> {"Afghanistan", "England"}; var listB = new List<string> {"afg"}; listA = listA.Where(x => listB.Any(k => x.IndexOf(k, StringComparison.OrdinalIgnoreCase) > -1)).ToList(); instead of x.IndexOf(k, StringComparison.Ordinal).

Answer 3

Try a simple Where statement with checking all the filters inside as so:

<div class="mf-container">
  <div class="mf-content">
    <div class="row">
      <div class="mf-third mf-center">
        <img src="img/qualifications/gimp_g.png" class="mf-pic-unique mf-pic-
          shadow mf-margin-top" id="gimp" alt="about gimp">
        <p id="qGimp" class="mf-off-black-text"> </p>
      </div>
      <div class="mf-third mf-margin-top">
        <p class="mf-center mf-off-black-text">Click on an image to learn more 
          about each technology</p>
      </div>
      <div class="mf-third mf-center">
        <img src="img/qualifications/inkscape_G.png" class="mf-pic-unique mf-
          pic-shadow mf-margin-top" id="inkscape" alt="about inkscape">
        <p id="qInkscape" class="mf-off-black-text"> </p>
      </div>
    </div>  
  </div>
</div>
